Magnetic nanocomposite materials and passive components formed therewith

Abstract

A method apparatus and material are described for radio frequency passives and antennas. In one example, an electronic component has a synthesized magnetic nanocomposite material with aligned magnetic domains, a conductor embedded within the nanocomposite material, and contact pads extending through the nanocomposite material to connect to the conductor.

What is claimed is: 
     
       1. An electronic component comprising:
 a synthesized magnetic nanocomposite material with aligned magnetic domains, wherein the nanocomposite material comprises magnetic nanoparticles comprising a silica passivation layer coated with an aminosilane and a silane different from the aminosilane, wherein an amine endgroup of the aminosilane is covalently linked to an endgroup of the silane different from the aminosilane; 
 a conductor embedded within the nanocomposite material; and 
 contact pads extending through the nanocomposite material to connect to the conductor. 
 
     
     
       2. The electronic component of  claim 1 , wherein the conductor is a copper strip, and wherein the contact pads are each at opposite ends of the strip to form an inductor. 
     
     
       3. The electronic component of  claim 2 , wherein the copper strip is linear to form a single turn inductor. 
     
     
       4. The electronic component of  claim 1 , further comprising a substrate to carry the nanocomposite material and the conductor and dielectric walls to isolate and contain the nanocomposite material. 
     
     
       5. The electronic component of  claim 1 , wherein the silane that is different than the amnisilane is 3-glycidyloxypropyltrimethoxysilane. 
     
     
       6. The electronic component of  claim 1 , wherein the aminosilane is N-aminoethyl-3-aminopropyltrimethoxy-silane. 
     
     
       7. The electronic component of  claim 6 , wherein the silane that is different than the amnisilane is 3-glycidyloxypropyltrimethoxysilane.
